First we have to see in both cases what is the cost of one ticket
in the fist case 12.5/5=2.5
in the second case 20.16/8=2.52
therefore 5 tickets for 12.5 is the better deal
Step-by-step explanation:
the answer is:
x=180-90-70=20°
√2 is irrational
a rational number Q can be expressed in the form where a and b are integers.
- 18 = ⇒ rational
⇒ rational
3.14 = ⇒ rational
√2 = 1.414213562...... ⇒ irrational
I could help if I had a picture of the problem
